ok what .mdl missing,
I have just gone though all the models double cheeking them and double checked the .res too. everything seems fine.
This hase been running for a week now on the snarkcafe server with no problems from either the players or the server.

Any more specific info. What does the server Logs say ?
The map isn't anywhere near the ent limit, the wads included in the map.
Someone has pointed out i missed 2 sounds out in the .res list (retified in beta3) but that has no efect on servers so generally i need to know what the server Log says is missing to sort it out.
